one of the most common door lock types being fitted

What are the different door lock types?

A key first line of defence for any home is a good lock – but with so many door lock types, it can be tricky to choose one. Over half of Britons buy subpar door locks, making burglars’ lives much too easy.

To protect your home, family and valuables from thieves, it‘s crucial to install the right locks. Let‘s look at some of the best locks and when you might choose them.

What are the different door lock types?

There are some more common types of door locks that provide a good level of security for external doors. Often, these are recognisable, insurance-approved door locks. They’ll come tested against common theft tactics and will withstand a certain amount of force.

Mortice Deadlocks

The five-lever mortice deadlock is a robust type of door lock. It comes with the British Standard BS3621 kitemark that many insurance policies insist on – this way, you know it provides a minimum good level of protection. It’s a common choice for front doors and other exterior doors.

Mortice locks are installed on the edge of the door, with only the keyhole and faceplate visible, instead of the locking mechanism. You’ll often see a mortice deadlock installed on wooden doors. They’re also known as sash locks.

Multi-Point Locking System

Commonly seen on UPVC doors and composite doors, multi-point locking systems feature at least three locking points. These points work together to create a strong locking mechanism, often activated by lifting the door handle.

Multi-point systems extend from the bottom to the top of the door, giving added protection against brute force entry.  

Euro-cylinder lock

Euro-cylinder locks, also known as barrel locks, are another widespread lock for internal and external doors. They are simple to fit, coming in double cylinder, single cylinder and thumb turn varieties. Double cylinder Euro locks are operated by a key on both sides, while single cylinders typically only require a key on the external side.

Rim automatic deadlatch

Also known as night latches or Yale latches, rim automatic deadlatches are often fitted on the inside surface of the door. Then, they will operate with a key from the outside and by hand from the inside. A rim lock provides security by locking as the door closes, and can often be used in tandem with other kinds of door locks for added protection.

Deadbolt lock

Also known as deadlocks, deadbolts can be operated by a key from one or both sides. They don’t use a spring, so will not lock the door upon closing. They’re more commonly found on internal doors in offices and other places of work.

What other lock types can help protect my home?

Often, homeowners look for further locks for additional security. When that is the case, you might consider adding:

  • A night latch in addition to your primary locking mechanism
  • Doorknobs with a locking mechanism, especially on secure internal doors
  • Improving window and patio door locks, including multi-point locking mechanisms and bolts
  • Padlocks on external doors – for example, strong shackle padlocks often prevent entry to sheds and garages.

These locks should be used in addition to strong main locking mechanisms for maximum security. They’ll provide additional barriers to entry, especially helpful should a burglar overcome your main locking method. The additional peace of mind often makes the cost of a locksmith more than worth it.

What kind of lock should I get?

Whichever lock you choose, its primary goal should be to prevent break-ins. For that reason, it’s essential to choose robust locks that conform to minimum protection standards. If you need help choosing your type of door lock, get in touch today.
